Abstract

A fastener with a head at one end, a shank and a drill point at the opposite end. The shank is provided with a first and a second thread, which have their beginning as run-out into the back portion of the drill point flutes. The drill point has two opposing cutting edges with adjoining flutes that eject the drill shavings during drilling. The first and second thread extend a predetermined distance along the shank, at a predetermined height, toward the head. The first thread is positioned between the helical windings of the second thread. The second thread continues unbroken from said predetermined distance at a larger radial diameter terminating close to a conical portion on the underside of the head. Drilling commences until the threads penetrate a first object and engage into a supporting substrate. The large pitch of the thread profile enables the fastener to rapidly advance into the second object. The large pitch of the second thread allows a greater withdrawal strength of the installed fastener by providing a wide cavity between adjacent threads to engage more uninterrupted fiber in the supporting object.

Description

Lock firmware

This creation relates to a type of fastener, and more particularly to a screw that securely positions a plurality of objects together.

The beam-lifting structure refers to the structure of the building with a wooden frame structure, and the outer wall is made of a roller to form a metal panel, and then a plurality of fasteners (commonly known as screws) The panel is attached to a wooden structure. The conventional fastener comprises a head capable of applying the fastener to the torque rotating action, a rubber gasket made of a material of ethylene-propylene tri-copolymer, and a sharp rod. A helical thread that forms a deep peak inward and an end point for performing the penetrating action and initiating the embedding process. In general, fasteners are usually matched with an electric drill equipped with a special drive tool, and the special drive tool conforms to the contour of the head of the fastener. One of the most common head configurations is hexagonal, and the drive tool corresponds to a hexagon. The hexagonal shape is hexagonal. When the hexagonal head is mounted corresponding to the hexagonal concave driving tool, the tip of the fastener will be aligned with the metal panel, and the electric drill will be applied to pressurize the external force and drive the fastener. The tip penetrates into the metal panel. Once the metal panel is penetrated, the helical thread is combined with the straight wood structure until the entire length of the rod is completely drilled, and the rubber gasket is pressed against the metal panel to form a sealed Style.

The fasteners used in the beam-lifting structure are hardened steels that have been carbonized by high temperature and fire, and the color of the hardened steel is usually the same color as the metal panel of the exterior wall. The hardened steel must have a measurable and uniform size. Its appearance, as well as its physical properties such as tensile strength, elongation, hardness, etc., can be quickly installed into metal panels and wooden structures. The fasteners are mounted on the outside of the beam-lifting structure and are resistant to acid rain and extreme heat. And corrosive effects such as ultraviolet rays.

Manufacturers of conventional fasteners usually perform a plating treatment on the fastening surface to protect the fastener from corrosion. The plating procedure can be one of three methods: hot dip, mechanical plating, or electrochemical deposition. In the hot dip method, the fastener is immersed in the molten zinc pool, so that the surface of the fastener is coated with a thin layer of zinc, and the hot dip method is not easy to control the thickness of the thin layer of zinc formed in the crime, and usually The hot dip method is used to coat the surface of the nail, and the plating procedure of the screw is rarely used; the mechanical plating method is generally used for the fastener made of hardened steel, which rolls the fastener in a mixture of water, zinc powder and chemical substances. Until the surface of the fastener accumulates a predetermined thickness of zinc layer; electrochemical deposition is to immerse the fastener in a pool of water and zinc salts, and the fastener is charged, so that the zinc in the electrolyte is electrically adsorbed The surface of the hardened steel, the thickness of the zinc layer formed on the surface of the drum, is based on the length of time and current used in the electrochemical deposition.

However, the zinc layer formed on the surface of the fastener generally tends to accumulate at the tips of the ends of the fastener, that is, at the head and tip of the hexagon, in order to achieve a necessary zinc layer thickness on the rod. In turn, it is possible to avoid long-term corrosion, and instead cause excessive zinc plating on both ends of the fastener, because during the electroplating process, zinc is formed at the tip end of the fastener to cause acute angle passivation, so that the end of the fastener cannot be Through the metal panel. If the thickness of the plating is reduced, and zinc can be prevented from excessively accumulating at the end of the fastener, the fastener is prematurely corroded.

The author uses the electrochemical deposition method to electroplate the surface of the fastener. The inventors have found that when the diameter of the fastener is reduced and the length is increased, the aforementioned problem of excessive zinc accumulation is more serious. The occurrence of metal accumulation at the end poles of the occurrence often causes the piercing end of the fastener to fail to perform the action through the metal panel in an instant, which is unsatisfactory, which is particularly prone to occur in the type Kwikseal II fastener. The electroplating process, model Kwikseal II fasteners (10:2 aspect ratio), is very similar to other fasteners used in the construction industry to build beam-type structures. It is well known that fastener manufacturers. The fasteners are all electroplated.

The inventor of the present invention devised a fastener that was also used in a beam-lifting structure that would not be affected by the aforementioned excessive accumulation of zinc at both ends.

The main purpose of this creation is to provide a fastener that avoids the excessive formation of zinc at the tip end of the fastener during the plating process, thereby avoiding the process and time of delaying the assembly of the building material by the fastener.

For the above purposes, the creation of the lock can be said to be the model Kwikseal III, most of which are the same as the Kwikseal II fasteners, except that the tip of the creation lock is not as conventional. The sharp end points, the cutting-edge function of this creation is very similar to the function of the drill bit. Because it uses the cutting edge design of the model Kwikseal II, the hole is made in the metal panel, instead of the conventional one, the tip with an acute angle is used. Piercing the hole and reversing through experiments, the creation of the lock is not affected by the excessive accumulation of zinc, and forms a complete and appropriate zinc plating on the surface of the creation of the lock, and will not lock The unfavorable situation that the firmware creates a delay in the process of penetrating the metal fabric and penetrating the wood structure.

In order to further understand the structure, use and characteristics of this creation, we have a deeper and clearer understanding and understanding. The preferred embodiment is described below with reference to the following:

Referring to the drawings, various embodiments of the authoring lock firmware will be described with reference to the drawings. 1 is a threaded fastener according to the present invention, the structure of which is substantially as indicated by the symbol 10 of the present invention. The present invention is mainly composed of a proximal end portion 11 and a lower end portion 11 below the proximal end portion 11. The ring taper portion 12 and the rod portion 13 connected to the ring taper portion 12 are formed in common.

The distal end of the rod portion 13 is defined as a distal tip taper portion 14. The distal tip taper portion 14 defines a plurality of grooves 14F, and a distal end of the distal tip taper portion 14 is provided with a tip end 15. The first thread 16 and the second thread 17 are the starting points of the top end of the groove 14F of the distal tip tapered portion 14. The first thread 16 extends along the tapered section 14T of the surface of the distal tip tapered portion 14 and extends spirally toward the proximal end portion 11 in the axial direction of the proximal end portion 11, the first thread The height of 16 is increased by a constant height of a first height 16F, and its axial direction is parallel with a substantially cylindrical body portion 13. The approximate position of the above-mentioned rod portion 13 is referred to the reference numeral Ref. A in FIG. It is indicated that the first thread 16 is continuously spiraled along the rod portion 13 up to a predetermined axial position, the axial position being located on a plane perpendicular to the axial direction of the shaft portion 13, as referenced in FIG. As indicated by Ref. B, the first thread 16 is displaced from the relatively tight first height 16F to the more relaxed second height 16S and into the shaft portion 13.

In a preferred embodiment, the second thread 17 has a starting point relative to the starting point of the first thread 16, and the starting point of the second thread 17 is located in the tapered section 14T. And extending from the inside thereof to the proximal end portion 11 along the axial direction of the tapered portion 14T with a ring size identical to the first thread 16 described above, the second thread 17 being positioned between the ring and the ring And substantially equidistantly arranged with the pitch of the first thread 16 , the second thread 17 continuously spirally extending along the tapered section 14T to form a first height 17F, wherein the first height 17F is located The first height 16F of the first thread 16 is coplanar, as indicated by reference numeral Ref. A in FIG. The second thread 17 continuously extends spirally toward the end of the proximal head portion 11. The height of the second thread 17 is increased by a constant height from a first height 17F until a first height of the first thread 16 is reached. The predetermined axial position of the 16F coplanar, the second thread 17 is shifted from the first height 17F to the second height 17S by a constant radial distance. The second thread 17 extends helically along the stem portion 13 until adjacent the end of the proximal head portion 11, as indicated by reference numeral Ref. C in FIG.

The relative distribution between the first thread 16 and the second thread 17 described above is very important during the installation and after the installation. The structural strength of the inventive lock 10 is generally important in the building construction industry for a building. Whether the assembled material can be installed in an efficient manner is quite sensitive. The metal sheet 23 is attached to the frame assembly 25 and must have weather resistance for a relatively long period of time after installation. For the builder, the interruption of the installation speed during installation is often regarded as an expensive cost, and the structure After installation, the defective fastener 10 is often loosened due to the wind acting on the underside of the wall and the roofing sheet, resulting in a composite component 19 with a lock 10 (please refer to FIG. 6) and a metal sheet 23 The weather-resistant seal is damaged. It is disgusting that if the rainwater from the strong wind enters the building, it will cause damage inside the building and deterioration of the structural frame assembly 25.

There are many considerations for building materials during the installation process. The fastener 10 must be able to successfully and quickly penetrate the metal roof or wall sheet, and the thickness of the sheet generally used for construction is about 0.4mm to 0.5mm. The shape of most of the sheets is roughly set to a flat surface, and the flat surface facilitates the proper mounting and positioning of the fastener 10. The speed of the fastener 10 running through the sheet must be completed through a sheet of material every 0.20 seconds, and at most 0.50 seconds to perform the penetrating action. After the sheet 10 is inserted through the sheet, the metal sheet 23 is continuously passed through without stopping. After the metal sheet 23 is penetrated, the fastener 10 can reach and be coupled to the frame assembly 25, and the fastener 10 must continue to be drilled at a fixed rate without bending, breaking, or peeling from the substrate, etc. The situation until the final stability is safely positioned on the surface of the wall or roof metal sheet 23. In contrast, the gasket 20 must be properly locked by the fastener 10 to avoid a displacement of the underside of the proximal head 11 of the fastener 10, thereby preventing moisture from being loaded by the fasteners on the sheet. Ten drilled holes enter the interior of the building.

In another preferred embodiment, the present inventive locking member 10 is provided with a distal tip taper portion 14 having an end point with the tip end 15 as a starting point, and the tip end 15 The sharpness and hardness have been confirmed by the verification, and the action of penetrating the metal sheet 23 can be completed in an average time of 0.2 to 0.3 seconds. When the distal tip taper portion 14 initially clears a positioning hole, the first thread After the 16 and the second thread 17 are in contact with the positioning hole, they are penetrated and combined with the metal sheet 23 and the frame assembly 25, respectively. The second thread 17 of the first thread 16 has the same pitch at the beginning, and provides a symmetrical supporting force of the rod portion 13 for the initial thread to be smoothly and uninterruptedly screwed into the frame assembly 25. The first heights 16F and 17F of the first thread 16 and the second thread 17 of the same specification can provide the above-mentioned rod body 13 with an equal support force, so that the above-mentioned fastener 10 is prevented from being attached to the sheet at a sharp angle.

When the fastener 10 is to be further inserted into the substrate in the structure, the first heights 16F and 17F of the first thread 16 and the second thread 17 are respectively converted to the second heights 16S and 17S, and the second heights 16S and 17S are respectively The first heights 16F and 17F can be tracked in the correspondingly formed thread grooves in the substrate, and the second height 17S enables the fastener 10 to have a radial bond with the substrate, thereby The fastener 10 provides a higher pull strength. The thread groove can also avoid an excessive asymmetric lateral force on the periphery of the rod portion 13, thereby avoiding an acute angle between the mounted fastener 10 and the plane of the metal sheet 23, and the above The two heights 17S are capable of reinforcing the tensile strength of the above-mentioned rod portion 13 with a radial force.

The creation lock 10 is a powerful screw design for the manufacturing industry. The typical tapered portion has a screw taper and a tip end, and is connected to the pre-threaded rod portion 13 and can be integrally molded through a mold model. The manufacturing process of the screw can be divided into three types of operations. First, the tip taper of the tapered section 14T and the tip end of the distal tip taper 14 are respectively formed at different stages, and the two are formed before the thread is formed. It has been produced in such a way that it does not undergo rolling a large amount of steel material into a cone with a tip, which extends the life of the mold model, and the mold model is not passivated or worn too quickly. On the contrary, it can keep the mold model sharp and long-lasting, and can make the screw with a smooth and sharp angle. At the same time, it can also delete the cutting step at the tip, that is, when the screw enters the metal sheet. The spiral shavings provided by the distal tip taper 14 are removed. The process steps of performing the groove cutting at the tip are not easy to handle and are prone to undesired results, often cutting off the tip end of the lock 10 or cutting the thread of the rod portion 13 to cause the thread to be discontinuous. Spiral shavings are usually kept undamaged, embedded, and contain gaskets to create a moisture infiltration. The distal tip taper 14 described above will create smaller shavings and eliminate the dent problems created by the shavings, allowing the gasket to compete with the substrate to be screwed.

In addition, in a preferred embodiment, the inventive composite component 19 includes a locking component 10 and a sealing gasket 20, which are combined by a metal and an elastic rubber material 22 to facilitate weathering installation. A single gasket 20 is formed on the gasket body 20 and is adjacent to the axial position of the proximal head portion 11. Referring to FIG. 5, the proximal head portion 11 is An advantage of providing the tapered portion at the lower side is that the annular tapered portion 12 is centered on the gasket 20, and the gasket 20 is sandwiched by the metal sheet 23, and the composite unit 19 is mounted. The structure of the gasket 20 after being sandwiched between the above-mentioned fastener 10 and the metal sheet 23 is as shown in FIG. 6. When the above-mentioned elastic rubber material 22 is pressed against the metal sheet 23, it will seal the above. The peripheral edge 26 of the gasket 20 is sealed and resistant to the infiltration of moisture.

That is, the pressing action of the above-mentioned elastic rubber material 22 enables the sealing material to be plastically deformed into the internal space without limitation, and is mounted by the properties of the material itself, for example, the metal plate of the above-mentioned gasket 20 The hole 18 formed in the material 23, that is, the space between the radial wall surface 27 and the radial wall surface 27, the surface of the annular cone portion 12 of the proximal end portion 11, is started by the tip end 15 of the above-mentioned fastener 10. Drilling through the holes 18 formed in the sheet can help prevent moisture from penetrating into the interior of the building. In order for the elastic rubber material 22 to be made into the gasket 20, it is necessary to conduct careful research. The gasket 20 thus produced can resist the deterioration caused by ultraviolet radiation and ozone in the atmosphere, and allows the fastener and the composite component 19 to cooperate with other materials used in construction, and can provide weather resistance in a certain period of time. . It can be understood that the composite metal 24 bonded to the elastic material of the gasket 20 can also be matched with other materials used in construction. The composite metal 24 of the gasket 20 and the elastic component must be compatible with each other to maintain a bonded state throughout use, so that the composite metal 24 remains positioned below the proximal head 11 of the fastener 10, ensuring an elastic rubber material. 22 maintains a coaxial line 21 with the composite metal 24 to prevent undesired displacement of the gasket 20 from below the proximal head 11 of the composite assembly 19.

Building installation problems, structural integrity issues, and weatherability problems can be solved and overcome by using the creative locks 10 in buildings. It is obvious that those with ordinary knowledge in the field can Various modifications to the various embodiments described above are made without departing from the scope of the invention. Therefore, the present sealing gasket 20 does not have to be combined with other metal components, but can be integrally molded from a flexible material, and the original rod body portion 13 can extend below the receiving portion of the proximal head portion 11. Instead of having to provide a ring taper 12, the shape of the present proximal head 11 can be set to a variety of different conventional contours, such as a large circle, a disk shape, and the like. Therefore, all such obvious changes and modifications should be included in the scope of this creation, that is, the scope of this creation is only limited by the scope of the patent application.

The above-mentioned embodiments are only used to facilitate the description of the present invention and are not limited. In the spirit of the creative spirit, all kinds of simple deformations and modifications made by the skilled person in this industry according to the scope of the patent application and the creative description of the creation should still be It is included in the scope of the following patent application.
